Attention-deficit/hyperactivity disorder (ADHD) is highly co-morbid across the life span. However, co-morbidity is not uniform across time; individual co-morbid conditions tend to occur at different times developmentally, with rates often reflecting lifetime occurrence (Slide 1). In addition to changes in the rates of co-morbidity, the nature of co-morbidity may also differ in late adolescence/adulthood, when co-morbid conditions can be especially impairing (eg, antisocial disorder, substance use disorder [SUD], more severe mood disorders).
